filo all whom t may concern:

lie it known that l, @nennen "l". ideenanniv, n cititen ot the Unitedtates, residing at lWlnterbury, in the county ot liteit lieven und @teteoil onnecticut, lieve invented a. new and 'usetul improvement ihHeading-Machines, oit which the itollovving is a specification.

Yllhis invention relates to the inechnnism which is provided -ioradjusting the punch holder ott n metal heading machine. ln dou ble ortriple stroke machines olli' this cherncter the punches are mounted on aslide which is carried back and 'forth horizontnlly by :t rnm that isreciproeated by the crank shaft, and is moved up and down verticnlly inthe front end ot the horizontally movable rain by a. connection trom ncom on the driving shat't, so -thst on one horivnrd movement of thehorizontnlly' movable rain one punch will operate on the stoclc held bythe dies, :ind on the following move* inent iiorwnrd of the rsni anotherpunch will operate on the stoclr.

The object of this invention is to provide at siinple and convenientmeans by which the punch holder can be adjusted horizontelly very finelyso that the punches will nccurutely eline with the dies and properlyattaining this end the punch holder is mounted inn block that, when themeans clampin the holder to the slide are loosened, can he movedsidewise in either-.direction in en opening in the slide by means ofthreaded Wedge rods which pass up through theslide and are provided`with nuts that are accessible from the top.

The invention is particularly adapted to und is shown and describedherein as applied to a double stroke heading machine of the type set:forth in United States Letters Patent No. 926,170, dated June 29, 1909.

Figure 1 of the accompanying drawings Ashows n vertical section of thehorizontally nlovnble ram, and n side elevation of the verticnllymovable slide carried thereby and the mechanisms for imparting ehorizontal rcciprocation to the former and a.

vertical reciprocutionl to the-latter, of such e double stroke headingmachine. Fig. 2

shows n plan of the punch ram and slide and' the mechanisms forreciprocating these parts. Fig. 3 shows a front view of .the verticallymovable slide and the punch .any heck face of the punch holder' is estein i4.

ln this type ot in'achines the rain l it moved bach and torthhorizontally by ineens ot a lerianlr rod 2 that is thrown by the prent:The slide t is moved up and down 1n a guidexvsyin the liront end ot the'rem hy menus ot rocher mans t on at shaft t which hais s rocher arm 7that is thrown by the connecting bar which is reciprocated h' the cam 5ton the driving shaft t0, (Fig. ll 'These mechanisms tor importing nhorizontal reciprocation to both the mm and slide and a verticalreciprocation to the slide are Well lmown and nre substnntislly the same:is shown in the patent referred to.

The unches l1 and 12 are fastened in the front nce of the punch holdingbloei: 13 in desired manner; Projecting from the This stem extends intoand fits an opening in ,a block 15 which is' movable horizontally on onopening 16 in the vertical slide. The side edges of this block, whichholds the stem of the punch holder, are inclined and engaging theseinclined edges are the inclined edges of rods 17 which extendl from the`top down through the vertical slide into the opening containing thepunch holder block.- The upper ends of these wedge rods are threaded andprovided with adjusting nuts 18 and clamping nuts 19. In order to adjustthe punch holding block horizontally to the correct position, the wedgerods are manipulated up and down by means of the nuts so that the blockis wedged either one side or the other as desired to eectthe result. Forinstance, if it is desired to move the block toward the left the nuts onthe vrod on the left are loosened so that the rod roden the right thenuts on the rod on thel left are a ain tightened so as to clamp theadjusting lock in the correct position.

After the holder carrying the punches has been correctly adjusted theholder is further fastened inkplace by clamping it to the slide by meanso the nut 20 on the bolt 21, which extends through 'an openin in thelower art of the punch holder w ich is slightly -argcr in diameter thanthe bolt, and by the nut 22 on the bolt 23 that extends through a hole,which is slightly larger in diameter than the bolt, in the upper partofthe punch holder. In order to allow this ad'ustment the holes throughthe punch holder are larger in diameter than the bolts, andl topreventthe punch holder from slip ing out of adjustment, by the reasonof the ooseness between the bolts and the walls of the holes which theyass through, at the upper end the punch older is provided with twoscrews 24 which are lset up a ainst the bolt 23.

To adjust the punches orizontall the screws 24 and the nuts 22 and 20are slightly loosened and then the holder is moved as necessary bymanipulating the block which contains the holder stem, by turningthenuts on the threaded wedge rods. After the horizontal adjustment isobtained in this manner the nuts 20 and 22 are tightened and then thescrews 24 are turned up. This insures a very exact adjustment of thepunches and securely holds them in such manner that they will not getoutof adjustment.

The invention claimed is:

1. The combination in a heading machine of a horizontally movable ram, averticall movable slide carried by the ram, a bloei movable horizontallyin the slide, means for movin said block horizontally in th slide, apunc holder carried by said block, and

means for clamping the punch holder to the slide.

2. The combination in a heading machine of a horizontally' movable ram,a verticall movable slide carried by thel ram, a bloc; with inclinededges movable horizontally in the slide, wedge rods and nuts carried bythe slide for adjusting said block horizonta ly', a punch holder carriedby said block, and nliens for clamping the punch holder to the s 1 e.

3. The combination in a heading machine of a slide, a block movablycarried by the slide, rods and nuts carried by the slide and adapted toadjust said block horizontally, a punch holder carried by said block,and ip eins for clamping the punch holder to the s 1 e.

4. The combination in a heading machine of a slide, a block withinclined edges movable horizontally v in the slide, rods with wedgesurfaces 'engaging the inclined edges of said block, nuts for adjustinsaid rods, a punch holder carried by sai block, and nlleans for clampingthe punch holder to the s ide.

5. The combination in a heading machineof a horizontally movable ram, avertically movable slide carried thereby,'a punch holder movablehorizontally on the face of the slide, a block movable in the slide foradjusting the punch holder horizontally, and rods extending up throughthe.A slide for wedging said b ock horizontally.
